Abstract
A novel type of side structure of ship is proposed, inspired by auxetic materials with a negative Poisson's ratio, for enhancing the crashworthiness of double-hull vessels. Three different unit cells (VRE, HRE, and ARR) are designed and numerical simulation is conducted to demonstrate their resistance to collision. A comparative study on the crashworthiness of the proposed side structures and those of traditional side structures (double hull, X-core, and Y-core) is performed and a superior capability of energy absorption and collision resistance of the proposed side structures is observed. These findings demonstrated a potential for auxetic-based structures to be applied as a collision resistance structure implemented in various protective structures.
期刊介绍:
This journal aims to provide a medium for presentation and discussion of the latest developments in research, design, fabrication and in-service experience relating to marine structures, i.e., all structures of steel, concrete, light alloy or composite construction having an interface with the sea, including ships, fixed and mobile offshore platforms, submarine and submersibles, pipelines, subsea systems for shallow and deep ocean operations and coastal structures such as piers.
